Control de la virulencia de cepas patógenas de Escherichia coli por antimicrobianos naturales
Palabras clave:
biopelícula, swarming, E. coli, Factores de virulencia E. coli O104:H4Resumen
Varios grupos de Escherichia coli pueden causar enfermedades con alta mortalidad en el humano, facilitando esta capacidad por mecanismos bacterianos que permiten su colonización y persistencia. Se han desarrollado tratamientos para su control, sin embargo, debido a su eficacia incompleta y a tendencias actuales, se está contemplando el uso de compuestos naturales antimicrobianos. En este trabajo se estudió la actividad del orégano mexicano, palo de Brasil y sus principales componentes antimicrobianos sobre el crecimiento, movilidad swarming, producción de biopelículas y expresión de genes de virulencia de E. coli enterohemorrágica, E. coli enteroagregativa y E. coli shiga-toxigénica EAEC O104:H4.
